No, it doesn't. It says that depression is a useful trait for ruminating over, and thereby solving, social dilemmas, not that the life is really as bleak as it seems when you're depressed.
Depressions/recessions are like forest fires, necessary evils that purge old models to make way for new ones. It's the best time to innovate and impact the world.
One of my dreams is to write an article worthy of being published in Scientific American, and getting it published there. SciAm consistently impresses me - they'll break new and groundbreaking things, but what's more impressive to me is how they avoid not giving into fluff the way many other publications do. And they make science pretty accessible and interesting. I've never written as more than a semi-professional hobby, but I'd love to put some of my research together well enough to get into the magazine at some point.
Don't get me wrong. I love speculation. Speculation drives science, and I don't think any interesting scientific idea can ever be conclusively "proven". Just, what's this article doing in SciAm? For an idea to get into SciAm is a big score because the idea has matured and seems significant. This one just sounds like something a couple guys would kick around over a beer without really knowing much about the topic. See my comments elsewhere on this page for specific, well-known problems that the article doesn't address.
Interesting idea, that depression is useful for ruminating. But, the reasoning seems premised on the idea that depressions are triggered by stressful events like discovering that your spouse has been unfaithful. Doesn't most depression occur due to seasonal changes such as the length of the day? (Hence depressions that occur at the same time each year, the effectiveness of treatments involving exposure to light at certain times of the day, etc.) The noteworthy, puzzling thing about depression is that it comes "out of the blue", for no apparent reason, not in response to circumstances that would explain a negative emotion. Also, when it lifts, there is similarly no apparent explanation. A problem did not get resolved; a rumination did not complete.
Another problem with the theory: a major symptom of depression is inability to concentrate. When you're depressed, it's like your IQ takes a 30-point hit. You become much worse at thinking things through.
That seems to fit the article. If someone is depressed about their cheating spouse, and the person is spending all of their thought process cycles on that, you wouldn't expect them to be good at math problems, or even other social problems. The article describes depression as very focused thought, so the ability to do anything else would presumeably suffer.
I wonder if you could resolve it using something like this.
Depression still exists due to the evolutionary reasons described in the article. However, since depression is caused by certain reactions in the brain, other things can cause depression.
This explanation of depression makes sense: My wife, who owns a gas station went into a depression when I told her about the latest developments in electric vehicles and how it would turn her job into a nonsense in the near future. Because she could not object to the situation, she had no other way but adapt to it and later came a real clinical depression, all because of what I reminded her.
The problem is that what you are ruminating over is probably not something that can be fixed by thinking. For instance if her husband is cheating on her, the woman should confront him. So depression would be adaptive only for certain kinds of problems. Perhaps we over use it because in more primitive conditions we would be constantly reacting to life and would be acting on instinct most of the time.

The points in this article sound logical to me and also useful. Dismissing them as "pure speculation" does not seem justified.

Just a guess though.
